As previously mentioned, Gollancz are publishing an omnibus of the first three Stainless Steel Rat novels in the UK. Amazon are listing it as having a publication date of 20th November 2008. There’s also a cover image – see below.
If you click on Amazon’s ‘see larger image‘ link, you can see that the title and the Rat image seem to have a holographic foil effect.
Personally, I’m not sure about this cover design, but there’s time for a change before November — if that really is the publication date: there still doesn’t seem to be any mention of it on the Orion Group website.
